The Seven Pre comes with 4 line level RCA inputs, a phono input for vinyl replay and a tape loop, as well as the mono/stereo switch, mute switch, earth lift switch, silver RCA sockets and non ferrous case like the Seven Phono and Line. Of course this too is made in the UK. It also has fitted a very high quality Elma selector switch and a close tolerance Noble volume control.
The phono stage featured in the Seven Pre is a brand new design and can be ordered as either MM (48dB gain), MC (68dB) or MC high gain for use with low output cartridges, with 74dB gain. This is is configurable at time of ordering.
The Seven Pre's line stage, being identical to the stand-alone Seven Line, provides up to +15dB of gain. The output stage is a very low impedance high current design, which enables it to be used with any power amplifier, whether transistor or valve. Additional partitioning has been employed internally to help reduce the disruptive effect of magnetic, mechanical and electrical fields for the critical aspects of the circuit. Note: All Sevens can be specified with 20dB, 26dB or a custom MC gain setting at time of ordering.
